Busy Philipps Flies to Comfort Michelle Williams on the 10th Anniversary of Heath Ledger's Death

Best friends are there to cheer you up and lift you up when you're down, and that's exactly what Busy Philipps did for Michelle Williams on the 10-year anniversary of Heath Ledger's death. On Monday, Busy flew out of town to be by her best friend's side during the difficult day. The actress later shared an Instagram photo of Michelle resting her head on hers, writing, "It's ok."

Michelle and Heath fell in love after meeting on the set of Brokeback Mountain in 2004. They had a child together, a daughter named Matilda, but broke up in 2007, a year before Heath tragically passed away. Other stars who shared touching tributes to the late actor included Naomi Watts and Lily Cole.
